What's in Wickenburg's water

Nitrate

Violation on record

Legal limit10 ppm

3 EPA violations on record (most recent 2023). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.

Haloacetic Acids (HAA5)

Violation on record

Legal limit60 ppb

1 EPA violation on record (most recent 2023). HAA5 are a second group of chlorine disinfection byproducts formed when chlorine reacts with organic matter in water. Long-term exposure is associated with increased cancer risk and possible developmental effects. They commonly occur together with trihalomethanes.

Total Trihalomethanes (TTHM)

Violation on record

Legal limit80 ppb

1 EPA violation on record (most recent 2023). TTHM form when chlorine used to disinfect water reacts with natural organic matter. Long-term exposure has been linked to increased cancer risk and to harm in pregnancy. Levels often rise in warmer months and in systems with more organic material.

Water hardness

very hard

Wickenburg's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
